My invention relates to a new and useful combination of mechanical and liquid elements to produce a wash, cleaning drying bluing, starching, and ironing combination,

5 whereby flat goods may be completely launendless wire mesh conveyors adjacent and traveling in the same direction and in contact with each other for a portion of their length, thence separating and divergmg, thence converging and agaln traveling parallel to each/other; second, to have these washed, rinsed, blued, and starched as de-.

conveyors so mounted upon the rollers that material fed between them will pass between brushes, then pass downward into the suds or first tank and under a series of heaters, thence upward over a roller, thence downwardinto a rinsing or second tank and -under heaters as before, and so on until sired, then through a drying compartment provided with steam coils, thence out of the compartment and delivered on the platen of a flat work ironing machine; third, to have the tanks containing the different cleansing and treating liquids project outward beyond the sides of the machine, so that the condition of the liquids may be seen while the machine is in operation; fourth, to provide meansv for regulating the force of the beaters, and the tension of the conveyors upon the rollers, also a practical transmission system for applying power to the several parts of the device; fifth, to provide a means for filling and emptying the tanks as the condition of the work requires.

I attain these objects by the mechanism shown in the accompanying drawings in which Fig. 1, is a plan of the washer and part of the drier;

The specific construction of my present machine comprises a built up frame of wood and medal, for the purpose of mounting and operating the different elements, but I do not confine myself to this particular style of frame, as other construction s would be equally adapted to the purpose. In the present frame I employ a series of posts 1 with longitudinal side ribbons 2 outside and adjacent the bottom thereof. Upper ribbons 3 inside of the posts 1 are adapted for journaling the trunnions 5 of theidler rolls 6, and the shafts 7 of the drive rolls 8, for mounting the two wiremesh conveyors 9 and 10, hereinaftermore particularly described. An intermediate ribbon 4 similar to 2 and 3 is disposed inside of the posts at a point adapted to support tanks or liquid 1112 and 13. Transverse beams 14 extend from sideto side and are secured to the edge of the posts 1, and similar beams 15 are located below and contiguous the ribbons 4 for adding rigidity to the frame, andan additional support for the. tanks. Said tanks may be constructed of any suitable material, sheet. copperpreferred, and are of rectangular base and of suflicient depth for holding liquids for sudsing, rinsing, and bluing, also starching if required in treating the material to be laundered. Only three tanks are shown in the drawings, but it is obvious that any! number may be employed. These tanks may be filled and emptied in various ways,

but I prefer filling by a force pump 16 under each tank, and emptying through a drain pipe 17. To theposts l on the outside and adjacent the bottom, on both sides of the frame journal boxes 18 are secured, and within the boxes shafts 19 are revolubly disposed. Below the center of the tanks longitudinally of the machine, eccentrics 20 with upwardly extending cam rods 21 are mounted on the shafts 19 with the upper ends of the cam rods hingedly secured to the outer ends of plates 22. Depending from the lower surfaceof' said plates are a plurality of bell shaped cups 24 functioning as beaters upon the material to be treated.

' Under the front end of the washer an electrie motor 25 is located and connected by worm gear 26 to the shaft 19 on the right side of the machine. Upon the rear end of said shaft 19 a bevel gear 27 is secured which meshes with a similar gear 28 located at the lower end of a vertical shaft 29 whichextends upward and is journaled in a bracket box 30. Upon the upper end of the shaft 29 a bevel gear 31 is secured which meshes with a pinion 32 secured to the rear end of a shaft 33 ournaled in boxes 34 on the posts 1. Said shaft 33 extends from front to rear on the right side of the machine and is connected to the four drive roller shafts 7 by worm gears 35 on the ends of the shafts 7 and worms 36 on the shaft 33. To connect the shaft 19 on the left side of the machine with the one on the right which is in connection with the motor 25 a cross shaft37 is connected by miter gears 38 to both shafts and journaled in boxes 39 secured to the central posts 1. A pair of shakers 40 above the conveyors, and 41 below them are revolubly mounted across the machine between the rear and next forward posts and are driven from a bevel gear 42 on the shaft 33 and a similar gear connected to 41 and the two are connected at the opposite end by a pair of spur gears 43. A roller 44 idles upon a shaft 45 secured in, and extending between the two rear frame posts 1. A tightener roller 46 is mounted at the upper end of a frame 47 by gudgeons 48 journaled in the frame, said frame is hinged to the front posts 1 by boxes 49, and an adjusting screw 50 provides a means for adjusting the ten sion of the lower conveyor belt 10. A side plate 51 is secured to the upper end of the front post 1 and to the front end of the right side ribbon 3, and a similar plate 52 is secured in a like manner to the left side of the machine with a shelf 53 projecting out ward, and upon which an electric motor 54 is mounted. A revoluble brush 55 the shaft 56 of which is at the right end journaled in the plate 51, and the left end extends through the plate 52 and is connected by belt 57 to the motor '54, it is disposed above and in contact with the conveyor belt 9. A similar brush 58 is located below the conveyor belt 10 and the outwardly extending shaft 59 by means of the belt 60 is connected to the motor'54, thereby the motor 54 drives both brushes for cleaning the conveyors. An idler roller 61 is mounted adjacent the tops of the two front posts 1 for carrying the lower conveyor, and supporting both conveyors when material is fed between them, and idler rollers 62 and 63 are journaled in and between the plates 51 and 52 for carrying the front end of the conveyor belt'9. Said belt 9 is constructed of wire mesh and is mounted upon a train of power and idler rollers. Starting at idler 62 it passes downward and backward under said roller, thence over idler 61 and down into suds tank 11 under the first idler 6, thence backward under second idler 6, and upward out of suds tank and over the first drive roller 8, thence downward into and out of rinsing tank 12, and over the second drive roller 8, thence into the bluing tank 13 and out over the third drive roller 8, thence backward between the shakers 40 and 41 and over the fourth drive roller 8, thence downward and under an idler 64 journaled in boxes 65 upon the front and adjacent the bottom of the drying compartment, thence into the compartment and backward under an idler 66, thence forward and partly around an' idler 67, thence upward and partly around a drive roller 68, thence backward and partly around a drive roller 69, thence forward and upward partly around an idler 7O thence over the top of an idler 71 and backward out of the dryer over an idler 72 journaled in'boxes 73 secured to the back of the dryer, thence under a tightener roller 74 journaled in adjustable boxes 75 slidably disposed in a vertical frame 76, thence over a square shaft 77 and backward partly around an idler 7 8, thence forward over idlers 79 and 80 on the top of the dryer and idler 63 at the front end of the veyor belt 10, is also of wire mesh, and

starting at the idler roller 61 is under and in contact with the conveyor 9 until they separate for return at the square shaft 77, then 110 turns upward and forward around an idler 81 journaled in brackets 82 extending backward from the frame 76, thence forward and downward under tightener roller 83, thence forward under an idler roller 84 and upward over idler 44, and forward under the tightener roller 46, thence upward and backward to the place of beginning at roller 61. The aforesaid plates 22 adapted to carry the rubber cups or beaters 24 as they are reeiprocated by the eccentries 20 are mounted each upon four vertical guide rods 85 secured to the top of the ribbons 3, thereby steadying but not rigidly guiding the heaters. The drying compartment, which is a rectangular cabinet, is provided with a plurality of horizontal series of steam pipes 86-87 and 88 positioned between the lines of the conveyors and coupled to supply and discharge means in the usual manner. An exhaust fan 90 is located centrally under the dryer adapted to draw downward the heat from the pipes through the conveyors as the goods are carried back and forth within the compartment.

Two circulating fans 91 and 92 are located across the compartment in vertical alignment withthe fan 90, for distributing the hot air between the lines of the conveyors.

An endless belt conveyor comprising a belt 93 mounted on rollers 94 and 95 revolubly disposed in a frame 96, between the rear end of the conveyors 9 and 10 and a flat work ironer B delivers the work to the platen of the ironer; power is transmitted to the conveyor through a spur gear 97 on the shaft of 94 meshing with a similar spur gear 98 on the shaft of roller 81", which is driven by the wire mesh conveyor belt 10. Two steam pipes 99 and 100vare located forward frame post 1A and extend across the machine, 99

above the conveyor 9, and below the conveyor, 10, these pipes are perforated next to the conveyors, adapted to deliver jets of steam against material carried between the conveyors, thereby assisting in the process of cleansing. The steam may be supplied from any convenient source.

To use my machine, fill the tanks with liquids adapted to'the purpose of laundering the particular articles; start all the motors and turn on the steam to the dryer.

and pipe 100, then feed the goods between the conve ors 9 and 10 at thefront end of the machine, and the goods wilLtake the course indicated by the line of double arrows, passing through the tanks of liquid and under the beaters as before explained.-

The single arrows point out the return of the conveyors after the goods have been delivered to the flat work ironer.

Having thus explained my invention, I claim:

In a washing machine, the combination of a pair of perforated, flexible belts adapted to receive articles to be washed between them, a liquid receiving compartment, means for guiding said belts into and out of said compartment. a plurality of times, a pair of spaced rollers located outside of said compartment over which said belts pass, and

means for shaking said belts between said rollers to remove liquid adhering to said belts and to the articles carried between said belts.

In testimony whereof I aflix my si ature.
